It can detect the presence or absence of a text by matching it with a particular pattern, and also can split a pattern into one or more sub-patterns. The Python standard library provides a re module for regular expressions.

Run Code.
A regex is a special sequence of characters that defines a pattern for complex string-matching functionality. Earlier in this series, in the tutorial Strings and Character Data in Python, you learned how to define and manipulate string objects.

Regular expressions are essentially a specialized programming language embedded in Python. And you can interact with regular expressions via the built-in re module in Python. The following shows an example of a simple regular expression: '\d' Code language: Python (python)
In Python, regular expressions are supported by the re module. That means that if you want to start using them in your Python scripts, you have to import this module with the help of import: import re. OpenAI. The re library in Python provides several functions that make it a skill worth mastering.
